IMPROVEMENT IN CAR-COUPLINGS.

Specification forming part of Letters Patent N o. P713396, dated April18, 1876 application filed August 5, 1875.

' To all whom it may concern:

Be it known that I, GEORGE WORDEN, of Pittston, in the county of Luzerneand State of Pennsylvania, have invented certain new and usefulImprovements in Gar-Coupling; and I do hereby declare the following tobe a full, clear. and exact description of the invention, such as willenable others skilled in the art to which it pertains to make and useit, reference being had to the accompanying drawings, which form part ofthis specification:

My invention relates to car-couplings, and is designed as an improvementupon the several patents granted to me, respectively, J anuary 2, 1872,No. 122,509; December 31, 1872, N 0. 134,503; and May 5, 1874, No.150,454.

In the drawings, Figure 1 represents a plan view of my invention, andFig. 2 a longitudinal section of the same.

My invention consists in the appliances and devices hereinafter setforth and claimed.

A is the draw-head of a car, whose bellmouth narrows from its lip onevery side so as to present a throat of just sufficient vertf caldimensions as to allow the entrance of the coupling-link, and is sodesigned in order that the mechanical movement to which the pin isexposed may be as small as possible. By this means the pin will not bendunder the same pressure as if the throat a were larger. B is anysuitable casing, placed on the roof of the draw-head, which forms ahousing for the pinlever, and is provided with a longitudinal slot,extending through it and connecting with a corresponding slot in theroof of the drawhead. Playing in this slot b is the primary lever G,which is pivoted at the point 0 in the casing B, and it is ofsemi-diskal shapes that is, the line of direction of its outer surfaceis at an angle to that of its inner surface. The upper extremity servesas a fulcrum for the pin-lever D, which is provided with a suitablegroove-symbol, d, at its under side. The upper end of the pin-lever ispivoted in the head of the casing B, and is at an angle considerablyabove its lower extremity, where it is attached to the coupling-pin E.This pinlever may be provided at its top with any suitable means, d, forraising it. The weighted slide F I do not claim in this application,since it is the same as has been claimed in one of my preceding patents.

The link connecting with an opposing car striking the primary lever 0,causes it, through its eccentricity, to raise the pin-lever D, which isalso provided with an eccentric shoulder or lug, which latter lever atonce and easily raises the coupling-pin so that the link is allowed topass beyond the slot of the coupling-pin then the pin-lever, the forceoffered by the primary lever having been withdrawn by the passage of thelink,'falls back by its own gravity into itslongitudinal slot, carryingthe coupling-piu into its corresponding slot, thus coupling the carseffectually.

The mechanical appliance d on the pin-lever can be at any time sooperated as to cause the coupling-link to be loosed.

Thus it is manifest that the present invention is an improvement uponany of my previous ones, and forms the simplest of the series, since thenumber of the elements engaged are greatly decreased, and both the costof c011- struction, the greater simplicity, and the more positiveaction, all serve as strong features of improvement.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

In an automatic car-coupler, the curvedfaced primary lever or trigger O,pivoted at its top end in the casing B above the draw head A, andinclined lever D, constructed in its under edge with a curved slot orgroove, d, into which the end or nose of the trigger U enters andoperates said lever D and pin E by the passage of the incoming link, asdescribed.

In testimony that I claim the foregoing I have hereunto set my hand this3d day of August, 1875.
